Update Asp.Net Core Role Claim

Question

How i can change role claim and apply it in terms of one request in Asp.Net Core? I tried to use

_signInManager.RefreshSignInAsync(user);

But it only works after refreshing the page. Is there any way to update roles for user and change current principal in one request?

You could not change the Current ClaimsPrincipal directly.

To reflect the new claims, you could try _signInManager.CreateUserPrincipalAsync.

To check the new roles in the same request, you may try User.AddIdentity to explict add the new role claim to User.

                var roleName = Guid.NewGuid().ToString();                
            var r1 = User.IsInRole(roleName);

            var user = await _userManager.GetUserAsync(User);
            var role = await _roleManager.CreateAsync(new IdentityRole { Name = roleName });
            await _userManager.AddToRoleAsync(user, roleName);

            var claimsPrincipal = await _signInManager.CreateUserPrincipalAsync(user);
            var claims = claimsPrincipal.Claims.ToList();

            User.AddIdentity(new ClaimsIdentity(new List<Claim>() { claims.FirstOrDefault(c => c.Value == roleName) }));

            var r3 = User.IsInRole(roleName);
